How heat resistant is boron nitride

What is boron nitride?
Boron nitride is typically black, brown or dark red crystals with sphalerite structure and also excellent thermal conductivity. Its solidity is second just to ruby, a superhard product typically utilized as tool materials and also abrasives. Boron nitride has chemical resistance and also no disintegration by not natural acid and water. The boron nitrogen bond is barged in hot, focused alkali. Oxidation begins airborne at 1200 ℃. Decomposition begins at concerning 2700 ℃ in a vacuum cleaner. It is slightly soluble in warm acid as well as insoluble in cool water. The relative density is 2.29. The compressive stamina is 170 miles per hour. The maximum solution temperature is 900 ℃ in the oxidation atmosphere as well as 2800 ℃ in the non-active reduction atmosphere, yet the lubrication performance is inadequate at room temperature. Most properties of boron nitride are better than carbon products. For hexagonal boron nitride: the rubbing coefficient is shallow Great high-temperature security, great thermal shock resistance, high toughness, high thermal conductivity, reduced expansion coefficient, high resistivity, deterioration resistance, microwave or infrared transmission.

What is the role of boron nitride? Hexagonal boron nitride can make TiB2/BN composite ceramics, advanced refractories and also superhard material; separation rings for constant horizontal rolling, high-temperature immune lubricating substances and high-temperature layers. It is likewise a resources for synthesizing cubic boron nitride. In addition, it is additionally a really excellent high-temperature lubricating substance, which can be made use of as an element of self-lubricating bearings. Boron nitride has numerous physical buildings similar to graphite, called white graphite. It is similar to mica, talcum powder, as well as silicate; Fatty acids are jointly described as white solid lubricating substances. As a lubricant, boron nitride can be distributed in heat-resistant lubricating oil, water or solvent; It is splashed on the rubbing surface to develop a completely dry film after the solvent volatilizes and afterwards filled out the material, ceramic, as well as steel surface layers as a high-temperature resistant self-lubricating composite product. It is used in aerospace engineering, or the boron nitride powder can be directly coated on the overview rail surface. The boron nitride suspension oil is white or yellow. For that reason, it does not pollute fibre items in textile machinery and can be extensively used in the lubrication of artificial fiber fabric machinery.

Is Boron nitride hazardous to human body?
Boron nitride is not poisonous, yet boron nitride powder is a cloud of dirt harmful to human health and wellness. Boron nitride powder is literally inert and also will be damaging to health and wellness when ingested, inhaled, and also contacted with the skin and also eyes. Consuming or inhaling will create skin, breathing system, and also kidney flow conditions.

Price of boron nitride
Boron nitride particle dimension as well as purity will impact the product'' s rate, as well as the purchase volume can likewise affect the price of boron nitride. A huge quantity of huge quantity will be reduced. The cost of boron nitride can be discovered on our company'' s main web site.
